According to the damage estimation of the Tokyo metropolitan area earthquake, which was reviewed by the Tokyo Metropolitan Government for the first time in 10 years, the number of deaths and damage to buildings has decreased by more than 30% from the previous time due to the progress of earthquake resistance of buildings. By doing so, we hope to accelerate earthquake resistance, saying that damage can be further suppressed.
According to the damage estimation of the Tokyo metropolitan area earthquake, which was reviewed by the Tokyo Metropolitan Government for the first time in 10 years, the number of houses based on the current earthquake resistance standards has increased to more than 90%. It's too few.
The Tokyo Metropolitan Government has also announced estimates of how much damage it will reduce if measures are taken in the future.
According to this, if all houses in Tokyo are made earthquake-resistant based on the current standards, the death toll and damage to buildings can be reduced to about 40% of this assumption.
In addition, the economic damage estimated to be 21.56 trillion yen for buildings and infrastructure alone can be reduced to about three-quarters if countermeasures are taken.
In addition, the installation rate of "seismic breakers" that detect the strong shaking of an earthquake and automatically turn off the breaker has increased to half, and the initial fire extinguishing has been thoroughly carried out to prevent fires caused by an earthquake. It is said that the death toll and damage to buildings can be reduced to about 10% of the current assumption.
The capital plans to review the regional disaster prevention plan based on these estimates.
